Variable Frequency Drivesyog dav siv nyob rau hauv industrial tswj kev siv xws li kiv cua, twj, compressors thiab conveyors. Hauv ntau qhov chaw muaj kev lag luam,VFDsua haujlwm nyob rau hauv ib puag ncig hnyav nrog plua plav, av noo thiab lub zog tsis ruaj khov. Kev tiv thaiv kom raug yog ib qho tseem ceeb los txo qis kev poob qis, txhim kho kev ntseeg tau thiab txuas ntxiv lub neej kev pab cuam.
1. Tiv thaiv VFD los ntawm hmoov av
Plua plav tuaj yeem cuam tshuam cov cua sov dissipation thiab ua rau muaj teeb meem hauv kev rwb thaiv tsev, luv circuits lossis cov khoom tawg. Qhov no yog tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cement industries, mines, steel nroj tsuag thiab ntawv mills.
Yuav kom txo cov plua plavVFDyuav tsum tau muab tso rau hauv ib qho chaw huv, qhuav thiab zoo - cua tshuab hluav taws xob. Tsis txhob muab tso rau ze ntawm crushers, conveyors, mills lossis lwm yam khoom siv uas ua rau muaj plua plav ntau. Kev tu cov kiv cua txias tsis tu ncua, lim dej, cua ducts thiab txee saum npoo yog pom zoo.
RENLE RNHV series nruab nrab -voltageVFDyog IP30 tus qauv tiv thaiv chav kawm. Nyob ntawm cov kev ua haujlwm ua haujlwm txawm tias muaj kev tiv thaiv ntau dua tuaj yeem raug teev tseg.

2. Tsis txhob ntub dej thiab condensation
Cov dej noo tuaj yeem ua rau corrosion, degradation ntawm rwb thaiv tsev thiab hluav taws xob tsis ua haujlwm. Condensation yog qhov muaj kev phom sij ntau dua, vim tias cov tee dej tuaj yeem tsim rau ntawm Circuit Court boards, terminals lossis busbars.
RNHV series nruab nrab voltageVFDyuav tsum tau ua nyob rau hauv cov av noo ntawm 5% thiab 95% RH, tsis muaj condensation. Li no, lubVFDchav tsev yuav tsum qhuav thiab ventilated thiab yuav tsum tau tiv thaiv los ntawm dej los nag, chav, xau thiab corrosive gases.
Nyob rau hauv high humidity los yog ntau yam kub txawv qhov xwm txheej, cua txias, dehumidifiers los yog txee warmers yuav siv tau los tiv thaiv condensation nyob rau hauv lub txee.
3. Tsis txhob muaj qhov hloov pauv voltage mus txog VFD
Cov chaw lag luam feem ntau ntsib qhov tsis ruaj tsis khov, poob ntawm theem, surge voltage lossis voltage dips. Cov faults no yuav ua rauVFDtripping, lub cev muaj zog kaw, los yog cov khoom puas.
RNHV series nruab nrab voltageVFDmuaj qhov input voltage ntau ntawm -10% rau +10% thiab zaus kam rau ua ntawm ± 2%. Yog tias daim phiaj hluav taws xob hloov pauv ntau, lub zog hluav taws xob yuav tsum raug ntsuas ua ntej pib ua haujlwm. Cov khoom siv hluav taws xob zoo xws li kev tiv thaiv surge los yog input reactors yuav xav tau.
RNHV series nta ntau- kev tiv thaiv kev ua haujlwm xws li overvoltage, undervoltage, surge voltage, overheat, luv Circuit Court, overload thiab tiv thaiv theem poob.
4. Cia qhov chaw txaus rau kev teeb tsa thiab cua txias
A VFDmuab tawm cua sov thaum nws ua haujlwm, yog li qhov chaw teeb tsa thiab qhov cua yog qhov tseem ceeb heev. Yuav tsum tau muab chav txaus rau cov cua kub dissipation thiab tu. Tsis txhob nruab lub txee ze rau ntawm phab ntsa lossis qhov chaw cua sov.
Pom zoo tshem tawm rau RNHV series yog yam tsawg kawg nkaus 0.5 m saum lub txee, 0.8 m nyob tom qab, 0.6 m ib sab thiab 1.6 m nyob rau hauv pem hauv ntej.
Cov Tswv Yim Kho Txhua Hnub
Txhim khoVFDkev ntseeg tau, cov neeg siv yuav tsum tsis tu ncua xyuas cov ntsiab lus hauv qab no:
Xyuas seb lub txee puas raug kaw zoo.
Ntxuav cov ntxaij lim dej, kiv cua thiab cua ducts.
Xyuas cov cable nkag rau dej los yog hmoov av.
Tshawb xyuas cov ntaub ntawv ceeb toom thiab keeb kwm txhaum cai.
Xyuas ambient kub, av noo thiab qhov cua.
Paub meej tias daim phiaj hluav taws xob nyob hauv qhov kev tso cai.
